ORA-12504: TNS:listener was not given

Question

I created container orcl2 database with pluggable database pdborcl2. When I try to connect

SQL> connect system@pdborcl2

I get this error:

ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

My tnsnames.ora look as follows:

ORCL2 =  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
  (SERVER = DEDICATED)
  (SERVICE_NAME = orcl2.localhost))) 
PDBORCL2 = (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = pdborcl2.localhost)))

I can normally connect to orcl2 with:

SQL> connect system@orcl2

Answer 1

You have CONNECT DATA instead of CONNECT_DATA (space instead of underscore). Fix that, and try again.
